Abstract
PURPOSE: To reduce occurrence of the hetero-sound in terms of the acoustic sense by driving the diaphragm of the heneycomb-structure from the back side and at the same time driving directly the front skin layer of the diaphragm.
CONSTITUTION: Honeycomb-structure flat plate type diaphragm 11 featuring virtually a square shape is attached to the front side of frame 13 via edge 12. While, for example, four units of magnetic circuit 18 consisting of plate 14, yoke 15, permanent magnet 16 and center pole 17 are provided in the fixed arrangement to the back side of frame 13. At the same time, the rear edge of coil bobbin 20 with voice coil 19 wound at the outer circumference is inserted into circular gap 21 between plate 14 and pole 17, and the front edge part of bobbin 20 is connected to diaphragm 11. Thus four points of diaphragm 11 are driven simultaneously via each bobbin 20 and by the driving force of each coil 19 which is driven simultaneously at circuit 18.
